Multiple Monitors – Lcd Widescreen With Portrait Orientation?

I currently have a dell d630 laptop with standard hardware except 3 GB ram divided 1/2 with the two down below, docked and a 24 inch widescreen LCD monitor. (apologies in advance for the long lead to the question below)
My job requires that i remote into servers, use databases, use the intranet, use my own notes, check email, etc. When I started I thought the real-estate on the 24 inch would suffice. But I see now I would really like is to have a monitor dedicated to email, another for my notes pages and my center monitor for working. I spend alot of time restoring and minimizing windows.
The trouble is I do not really want two additional 24 monitors. what I would really need is two 17-20 inch widescreens oriented to portrait mode.
It looks like the dell drivers and/or vtbook, should most likely make that happen. my drivers allow the 24 inch to be “rotated.” The difficulty is that the monitors do not “pivot” it is not like i want to switch them back and forth. once they are in position that is fine.
Can you just unscrew the bracket and turn it 90 degrees and put it back on? Is there some other option? I really think the 120-130 dollar acer or viewsonic monitors would be more than fine, but my expertise is not hardware, nor windows.
To sum up, what i would like is three monitors. a 17,19 or 20 inch oriented in portrait next to my 24 inch which is landscape then another 17,19 or 20 inch oriented to portrait. As I would not be using those monitors to watch the discovery channel or anything I don’t want to be spending super big bucks just to get a “portrait” configuration.
I’m open to any suggestions. Another colleague swears by VTbook, but i’m open to whatever. I just don’t want to spend a fortune since it’s coming out of my own pocket.
Thanks in advance for any help.
